Cyclisation of 3 and 10 by lithium–halogen exchange followed by reduction with lithium aluminium hydride gives pyrrolo[1,2-a]indoles 11 and 13 respectively. Similar treatment of bromides 4a and 4b gives pyrido[1,2-a]indoles 12a and 12b.
通过锂-卤素交换反应将3和10环化,随后用锂铝氢还原,生成吡咯并[1,2-a]吲哚11和13。对溴化物4a和4b进行类似处理,得到吡啶并[1,2-a]吲哚12a和12b。
